same here in oz.in the 70's ford made a 2v head (detatchable manifold)for their 250's,then made a 200/250 iron head x-flow,then an allow head 200/250 x-flow(all in the 70's!)they then went on to make an over head cam inline 6 and now have a 320hp,turbo,alloy head 4 valve per cyl inline!!oz was always a 6cyl country with ford holden(gm)and chrysler trying to out do each other in the 6cyl stakes(great for the inline freak!!)gm released a 3 liter inline then put a turbo on it in hte 80's and chrysler had their hemi 6's which are still hard to beat and are still very desirable to own.
